Processing files larger than 2.2GB. - Linux

This is a discussion on Processing files larger than 2.2GB. - Linux ; I always used the following functions to process files:
fopen()
fclose()
fseek()
ftell()
fwrite()
fread()
fputc()
fgetc()
The limitation of (at least some of) these functions is the maximum
filesize of 2^31 bytes.
So, to solve this I use:
fopen64()
...

Processing files larger than 2.2GB.

The limitation of (at least some of) these functions is the maximum
filesize of 2^31 bytes.

So, to solve this I use:

fopen64()
fseeko64()
ftello64()

But for the other functions I can't find theire largefile equivalents.
Can I safely assume that they are compatibel?

Unfortunately, I can't find manpages for fopen64(), fseeko64() and
ftello64();
Where can I find more information about this matter?

You should read libc.info, possibly on your system in
/usr/share/info/libc.info

It describes how the 32 bit interface is automatically replaced by the
64 bit one if you compile with the correct flags, like
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

It also describes all those libc functions in detail.
